The JFET clippers are a really bad idea. The intent is to minimize negative excursions on the outputs, and they will do that, but the short circuit output current of the op amps is ≈40mA, so they waste a lot of power. They also put an unnecessary 1-5mA load on the op amps during positive swings.
Furthermore, they aren't necessary. The PNP emitter followers will clip negative excursions.
You also don't need U2 and U3, and the OPA2134s are overkill. TL072 or TL074 would work just fine for any of the op amps.
